Best Answer

No. Area of a circle (A) is given by the formula A=(3.14128)*(d/2)2.

Modifying the equation, you get:

d= square root of (4A/3.14128)

where d is directly proportional to the value of A and vice versa. Since there are

no other variables in the equation, it's not possible for two circles to have same

area but different diameter.

Q: Is it possible for 2 circles to have the same area but not the same diameter?

Yes

Yes.

Yes

Yes. The circles can be of different size. These are called concentric circles.

1^2 or 2^2 or 3^2 or 4^2.... and it goes on...where diameter of circle is equal to the side of square divided by square root of total numbers of circles.. eg : side of square = 10 no of circles = 2^2 square root = 2 therefore diameter = 10/2=5.

Yes

Every diameter of the same circle is the same length, and unless someone comes alongand stretches the circle when you're not looking, the diameter doesn't change.So...YES-----------I disagree...No they are not... all circles would be the same size if that were the case.What remains a constant is that all circles are 360 degrees.==================================The question doesn't ask about " ... the diameter of circles ... ".It asks about " ... the diameter of a circle ... ".The diameter of circles is not always the same, butthe diameter of any one circle is always the same.P.S.: This is not the place to debate the answer.The "discussion area" is.

No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.

Yes.

Yes.

Concentric circles have the same center. They are not necessarily the same size. If two concentric circles have the same area, then they are congruent, meaning they coincide when superimposed.

yes' if they contain the same circumference and diameter then they are congruent(:

Frankly, I haven't the slightest clue as to what you mean by "the same." The circumference of a circle is defined as pi x 2 x radius, or pi x diameter. The area is pi x radius squared. Therefore, for real circles, these values can only be the same if the diameter measure is the same as the radius squared. This works is the radius is 1 or 2.

YES!!! THey would be congruent circles; tjhat is appear to be the same size.
